Show all headers | View raw

Add a prototype of task_struct to fix below warning on arm64.

  CC      arch/arm64/kernel/probes/kprobes.o
In file included from /tmp/linux/arch/arm64/kernel/probes/kprobes.c:19:0:
/tmp/linux/include/linux/kasan.h:81:53: warning: 'struct task_struct' declared inside parameter list will not be visible outside of this definition or declaration
 static inline void kasan_unpoison_task_stack(struct task_struct *task) {}
                                                     ^~~~~~~~~~~
As same as other types (kmem_cache, page, and vm_struct)
this adds a prototype of task_struct data structure on
top of kasan.h.
